RUDOLPH KREIER, OF NEW YORK, N. Y., ASSIGNOR TO GEORGE STEOK, OF SAMEPLACE.

FOR PIANOS.

SPECIFICATION forming part of Letters Patent No. 248,477, dated October18, 1881.

Application filed July 16,1881. (No model.)

To all whom it may concern:

Be it known that I, RUDOLPH KRETER, of New York, in the State of NewYork, have invented a new and useful Improvement in MnsicBacks forUpright Piano-Fortes and Organs, of which the following is aspecification.

In the accompanying drawings, Figure I represents a front view of partof the front of an upright piano, showing the position of themusic-rack. Fig. II is a cross-section of the same. Fig. III is across-section showing the music-rack extended for supporting the musicbook or sheet.

Similar letters represent similar parts in all the figures.

A represents part of the front of an upright piano, and B the music-rackfitted into a suitable square or oblong opening made in said front A. i

To the lower end of the rack B, some little distance from its bottom,one or more links, 0, are hinged to the back of said rack, the otherends of which said links are hinged, at a. to the inner side of thepiano-front A, in a line with the bottom edge of the opening in saidfront A.

D is a spring attached to the inner side of the piano-front A, actingagainst the links 0.

The upper part of the music-rack is allowed to slide freely in theopening of the piano-front and is guided by a suitable guide, E, actingagainst the back of the music-rack B and attached to the inside of thepiano-front.

Near the upperend ofthe l ack B, atthesides, projections or stoppins nare provided, and at the sides of the opening, on the inside of thepiano-frontA, projections m are attached, upon which the pins n willrest when the music rack B is pulled out and extended ready to receivethe music, to stop the downward motion of said rack and to support thesame.

Near the bottom of the music-rack B an elongated projection, F, isprovided to support the music book or sheet.

WVhen the music-rack is not in use, and in a position shown in Fig. II,the guide E will support and press the upper part of the rack close totheinside'ofthepiano-frontA, and the spring D will act against the link0 close to its hinge a, keeping thereby the lower part of themusic-rackin position, and said music-rack B will have the appearance ofa countersunk panel in the piano-front A.

When the music-rack is to be used, its lower end is pulled out, when thelink 0 will guide and cause the same to move downward until the pins acome in contact with the fixed projections m. The spring D will then actagainst the bottom edge of the link (3, and thus keep the music-racksteady and in position. To move the music-rack back again the same mustbe partly moved upward when the action of the link 0 will guide the sameinto its proper place.

WVhen the link 0 is made of some thickness the top edge or top surfaceof the same will form a brace to hold the rack in its desired downwardposition, and the pins n and fixed project-ions m may be dispensed with;but I prefer the use and an arrangement of these pins n and projectionsmas greater security for holding and supporting the music-rack whenmoved outward and downward to support the music. It will be perceivedthat with this arrangement greater height of music-rack surface isobtained than the height or depth of the opening necessary for theaction of the sliding rack, and all appearance of hinges on the face ofthe piano-front is obviated.

What I claim as myinvention, and desire to secure by Letters Patent, is-

In the front of an upright piano or organ, a music-rack, B, the upperpart of which is free to move in a suitable opening in said pianofrontand hinged near its lower end to a link or links, 0, hinged to theinside of the pianofront, in combination with spring I) and guide E, andwith or without projecting stop-pins a and fixed projections m, thewhole being arranged to operate substantially in the manner and for thepurpose described.

RUDOLPH KRETER.
